AIP Electronics New Mass Air Flow Sensor Meter 3Pin MAF for 1999-2005 Buick Chevrolet and Pontiac 3.8L AFH50M-05 3 PIN OEM Fit MF50M05

The part was an exact fit for my 2000 Park Avenue. It came very well packaged, the part number was clearly stamped on it and it worked. One of the fine wires inside looked like a resistor instead of the fine wire like in the old part. I am not sure how that will be as far as longevity or performance, but I was looking for a way to keep an old car running for a couple more years without spending $100+ on a sensor. This was perfect. It takes a total of 5 minutes to install as long as you have the tamperproof star bit in your tool case.

I saved approximately $120 on buying this item through Amazon. I was thinking maybe it was not premium quality, but, when it arrived by FED EX to my door within 3 days and was put on the car it worked great! The car no longer spitters and sputters down the road and it appears to save gasoline. So in my opinion, this product was well worth it! Would recommend to anyone considering buying auto parts to use this seller.

Absolutely ecstatic about this. Was nervous about this, but I threw this in my 88 Fiero with a 3800 swap, and I can now shift gears with ease! The old MAF must've been why the RPMs were dropping off too fast when the clutch was depressed - made it horrible to shift, and it has been like that ever since I did the swap. Very happy - it works. Will update later if issues arise.

I bought this unit because of the price and trying to trouble shoot an intermittent hesitation problem. Installed it in the car and it worked (however did not fix the hesitation issue) for just over 3 months then started to act up and the engine would not idle after starting the engine again after a quick stop in a store. It did this several times as weather started to warm back up and then this issue became very consistent with the warmer weather. I reinstalled the original sensor and the engine now runs fine again (except for the original issue). Of course this happened right after the 90 day warranty was up. I would not recommend this unit.

Seems questionable whether this is working correctly. When flooring it, I occasionally get a lean ODB2 code from this sensor but only when flooring it. If you don't have a way to reset it this could be even more annoying.

very nice came before the due date always a good thing. and the price wow very nice . will shop with them again....

The air flow sensor fit my buick and fixed the problem of the car shutting off after I had been idling. This same part cost about $150 at my local Auto Zone. I highly recommend the air flow sensor and it arrived about a week after I ordered it.

This thing only lasted two weeks , the car wouldn't run and threw a mass air, or map sensor code so with the new sensor I $75. later had it toed cost me total of 320. They had to send the sensor I bought for the $79. core charge so now I can't even get my money back. Run from this product!
